new 'and useful This invention'A- relates t0 and particularlyimprovements 1n wrenches, t0 earoperated wrenches.l

ne object'of the present invention is to provide a novel and improveddevice of this character whereby the device is capable of use in rightor left handed work, or for straight forward operation.

Another' object of the present invention 1s to provide a novel andimproveddevice of this character which is simple in construction, cheapto manufacture, and easy and effective in its operation.

Other objects and advantages will be apparent from the followingdescription when taken inl connectionv withy the accompanying drawing.

In the drawing:

Figure 1 is aside elevation of a wrench made in accordance with myinvention.

Fig. 2 is a side elevation of the device, one side of the casing beingremoved to expse the'gearing.

ferring particularly to the ing drawing, 10 represents a caslngwhich 1sdivided longitudinally into two sectlons, said sections being detachablysecured together by means of thev screws 11. Formed longitudinallythrough the casing, and at oneA side of the center thereof, is a bore12, and` disposed through this bore Ais a shaft 13,A having on theportion within the, casing a worm 14. One end of this shaft, whichprojects beyond the end of the casing, is `formed with a squared portion15 for attachment of a socket member 16, whichv is adapted to engage thework to be operated upon.l The other end ofthe shaft extends a`considerable distance, beyond the other end of the casing and hasslidabl disposed thereon a sleeve 17, said sleeve ing formed with alongitudinal slot 18 for the reception of the laterally extending pin 19carried by the sa1 d shaft. Thus the sleeve is4 slidable longitudinallyon the shaft, but rotatable with the to the side on which the device isto accompanyshaft, as will be more particularly' pointed' outhereinafter. The other or outer end of the sleeve is formed with abifurcation, the inner end of Awhich terminates in a transverselydisposed circular opening 20, said bifurcation being represented by thecharacter 21. Removably disposed throughthe said opening 20, isatransversely dlsposed bar 22, one end of which is flattened, as shown at23, for passage longitudinally through the bifurcation to permit thecylindricaly portion of the bar to .be disposed within said opening. Bymeans of this bar the sleeve,v together with the shaft, can be rotatedtoturn the worm formed thereon.

Disposed transversely through the casing is a short shaft 24, theopposite ends of which project from the opposite sides of .the casing asshown at 25 and 26, respectively, for the attachment thereto of the before-mentioned socket member 16, accreding engaged with the work. On theintermediate portion of the shaft 24 there is formed a -worm wheel orgear 27 which meshes with the before-mentioned worm of the sh aft 13,whereby when said shaft 13 is rotated the a motion will be communicatedto thepshorter shaft 24, and thus operate the socket member thereon, andthe work with which it is engaged. The socket mem' r is provided with ascrew 28 by means of which it is held in its secure position 'on theends of the shafts.

Thus there is provided a device which is capable of being used tooperate on a piece of work, such as a nut, which is disposed on eitherthe right or left hand side of an object or can Joe operated straight infront of the operator, case necessitatingthe. ,application of thevsocket member to the end of thel shaft 13. In the other cases thesocket member is applied to one or the other end of the shorter shaft24. On the shaft 13, at each side of the worm v14 there is disposed afriction washer 14.

By shank of the device is thus rendered capable of being lengthened orshortened to permit the'toolto reach different distaucesto suit thecharacter of the work and the desires of the user.

yWhat lis claimed is:

reason of the slidable sleeve 17, the` sov as will be understood, thelatter having a worm formed thereon and within the last-named shaft, andmeans for rotatthe casing, a transverse shaft disposed in the saidsleeve.

through the Casing and having a worm wheel n testimony whereof, I afixmy signature meshing with the said worm, 'a sleeve slidin the presenceof two witnesses.
